Not medical advice

EZ Weight Tracker helps you log your weight and see where it is heading. It is not a medical device and does not diagnose, treat or prevent any condition. The AI coach gives general information and can be wrong. If you have health questions, an eating disorder, are pregnant, or plan a large change in weight, talk to a doctor first. In an emergency, call your local emergency number.

How the numbers are calculated

• Trend line: an exponentially weighted moving average of your entries, so that day-to-day swings from water and food weigh less than the direction over weeks.
• Goal date: an estimate that extends your recent trend to your goal weight. It changes as you log and is not a promise.
• BMI: weight in kilograms divided by height in metres squared, with the adult categories of the World Health Organization. BMI does not account for muscle mass, age, sex or body type and is not meant for children or during pregnancy.
